The review findings indicate that social networks play an important part in the management of long-term conditions. We found that social networks tend to be defined narrowly and are primarily used as a way of acknowledging the significance of context. There is insufficient discussion in the literature of the specific types of networks that support or undermine self-care as well as an understanding of the processes involved. This necessitates shifting the emphasis of self-care towards community and network-centred approaches, which may also prove more appropriate for engaging people in socially and economically deprived contexts.
